The invention relates to a sample color-imitating method of a terylene/cellulose fiber blended fabric, which comprises the following steps: (1) treating a customer sample with acid, and preliminarily determining a dyeing formula and process conditions of a polyester part in the blended fabric; (2) pretreating the blended fabric, dyeing polyester, washing and drying; (3) treating the dyed blended fabric to dissolve cellulose fibers, comparing the color difference until the color imitation of the polyester part is successful, and determining a dyeing formula and process conditions of the polyester part; (4) taking a plurality of pieces of the pretreated blended fabric, dyeing terylene according to the dyeing prescription and the process conditions of the terylene part determined in the step (3), and then dyeing cellulose fiber; (5) comparing the color difference until the cellulose fiber part succeeds in color imitation, and determining a dyeing formula and process conditions of the cellulose fiber part; the method has the advantages of small color difference and short time consumption, effectively solves the problems of difficult and slow color imitation of the small sample in the actual production, and the success rate of the multiple sample is almost 100 percent; the method is greatly helpful for printing and dyeing technicians and students in dyeing and finishing professionals to learn the color imitation of the polyester/cellulose fiber blended fabric sample. |
